Some researchers are suggesting that smell and taste be considered one sensory channel, not two.  A paper to be published in The Quarterly Review of Biology written by Mollo and 14 colleagues “proposes the unification of all chemosensory modalities into a single sense. . . . The paper thus envisages a rupture with what emerges as one of the most deeply rooted confirmation biases in the scientific literature: the differentiation between gustation (taste) and olfaction (smell). . . . ‘The time has come to abandon the differentiation between the chemical senses and start asking better questions about the complex, nuanced, and interconnected manners by which a vast variety of chemicals have become signals crucially important to survival,’ the authors write.”

An exhibit at the Museum of Craft and Design (San Francisco; February 12 to June 5, 2022, “Living with Scents”) focuses on scent-based experiences.  The show’s website reports that “researchers and practitioners, from the neurosciences to the humanities, have strived to gain a better understanding of the sense of smell, which deeply, yet often unknowingly, shapes the way we live: our eating habits, our social interactions, our emotions, memories, and even our well-being and safety. . . . scents may thus be purposefully used to improve many aspects of our lives. . . . In the hands of contemporary designers, whose job it is to consider the interactions of minds, bodies, and things, scents are mediated in innovative ways to raise a form of new sensory awareness. . . . Working with and around the sense of smell, taking into account its neurobiological, historical, social, and aesthetic specificities, these practitioners [whose works are being presented] attempt to change the way we relate to and interact with the world.”

Straffon and colleagues assessed people’s responses to artworks that they created.  The researchers report that “Self-made objects tend to be favored, remembered, valued, and ranked above and beyond objects that are not related to the self. On this basis, we set out to test whether the effects of self-relevance would apply to visual art, and via what mechanisms. In three studies, participants created abstract paintings that were then incorporated in a dot-probe task, pairing self-made and other-made stimuli. Our findings confirm that attention and preference are higher for self-made (vs. other-made) artworks.”

Using the Outdoor Recreation Valuation Tool (ORVal), developed at the University of Exeter, researchers have determined the values of parks, beaches, and other green spaces in the United Kingdom.  The investigators found that “small parks deliver ‘pound for pound’ the highest recreation value, and that good access to quality green spaces, the weather and dog ownership are key drivers of increased outdoor recreation. . . . Large country parks and beaches are generally the most valuable green spaces. People from ethnic minority backgrounds and in less affluent socioeconomic groups are less likely to engage in outdoor recreation, even when given the same recreation opportunities. . . . Dog owners are 4 times (3.7) more likely to use recreation spaces but having children does not significantly impact recreation habits. . . . Key drivers of recreation include the proximity of the site, ease of travel, whether the park is a mix of grass and woodland and the availability of car parks and children’s play areas.”

Birman and Ferguson increase our understanding of the cognitive effects of listening to music.  They report that their study participantswere randomly assigned to four different groups: silence (no music), classical music, rock, and the final group could choose any genre they liked. The California Verbal Learning Test—Second Edition (CVLT-II) was administered to assess participant’s memory. Anxiety was also assessed before and after the memory test to see whether the music had any effect. Generally, results suggested that music presence or genre had little tangible effect on memory or anxiety.”

Soininen and colleagues thoroughly investigated the repercussions of having green walls in Finnish offices.  They found that “air-circulating green walls may induce beneficial changes in a human microbiome. . . . The green walls (size 2 m × 1 m × 0.3 m) used in this study . . . circulate indoor air. They first absorb the indoor air through the plant roots and soilless substrate, then automated fans circulate the air back to the room. When the indoor air passes through the green wall, volatile organic compounds (VOC) are efficiently removed via biofiltration by microbes, plants and the growing medium. . . . Each green wall contains three plant taxa (heartleaf philodendron (Philodendron scandens), dragon tree (Dracaena sp.) and bird’s nest fern (Asplenium antiquum) growing altogether in 63 units. Each unit consists of two to four plant individuals. . . . Spending time in green wall rooms seems to be related to increasing abundance of health-supporting skin microbiota within a relatively short time period of two weeks.”  Previous research has identified positive cognitive and emotional effects of in-office green walls (and plants generally).

Jimenez and colleagues found a link between exposure to green space and higher levels of cognitive functioning. They report that, using data from 13,594 women (mean age 61), they determined that “increasing green space was associated with higher scores of overall cognition and psychomotor speed/attention. In contrast, there was no association between green space and learning/working memory. . . . Green space can decelerate cognitive decline by supporting physical activity, psychological restoration, or reducing exposure to air pollution. . . . Residential exposure to green space was assessed using the Normalized Difference Vegetation Index, a satellite-derived indicator of the quantity of ground vegetation. Landsat satellite data at 270-m and 1230-m buffers around each participants’ residential addresses in 2013 were used. . . . This difference in scores is similar to the difference observed in women 1 year apart in age in the data. . . . These findings suggest that increasing residential green space may be associated with modest benefits in cognition in middle-aged women.”

Macaulay lead a team that investigated mindfulness in nature settings.  The researchers report that “Before and after a 20-minute outdoor experience, participants . . . completed surveys. . . . Participants were randomly allocated to one of four engagement intervention groups: mindful engagement, directed engagement, mind wandering, and an unguided control group. . . . the unguided control group had the greatest level of attention restoration. . . . . Performance on the post-test attention task demonstrated that the unguided control group had the highest level of attention restoration during the nature experience, and that the directed engagement group had the lowest level of attention restoration. . . . the unguided control group did not have to use their phone during the outdoor experience: previous research shows that engaging with technology during an outdoor break is detrimental to attention restoration.”

What factors influence how we integrate information from multiple sources?  Scheller and Sui found that “When interacting with the environment, humans exhibit robust biases toward information that pertains to themselves: Self-relevant information is processed faster and yields more accurate responses than information linked to others. . . . the present findings suggest that social relevance can influence multisensory processing at both perceptual and postperceptual stages.”

Grabalov and Nordh investigated future roles for current cemeteries.  They share that “the role of cemeteries in cities under densification pressure, such as Oslo and Copenhagen, is shifting. . . . cemeteries have the potential to become more public in the future. Based on the empirical material, we expect the cemeteries in these cities to maintain their spiritual dimension while becoming . . . more multifunctional and more multicultural. Over time, their role could become more diversified. . . . We demonstrate the potential of cemeteries’ contribution to the urban environment as multifunctional public spaces – the trajectory envisioned by Oslo and Copenhagen’s municipalities. . . . the case of urban cemeteries demonstrates that public space can also accommodate spirituality and facilitate reflections and contemplations – necessary and often neglected qualities in contemporary cities under densification pressure. This case exemplifies the need for diverse public spaces and recognition of various urban lifestyles and choices”
